Why TriboDyn TRI-EX2 75W-140 is the ultimate gear oil
Patented Ceramic Coating Technology
Under extreme heat and pressure, the patented ceramic coating actively forms a self-lubricating protective film on metal surfaces, seeking out high-friction areas for superior boundary-layer protection.
Extreme Pressure & Shock Load Protection
Advanced sulfur-phosphorus EP additives combined with ceramic technology deliver unmatched protection under heavy towing, high torque, and severe shock loading conditions.
Highest Film Strength & Wear Protection
Superior film strength creates a durable barrier that dramatically reduces metal-to-metal contact, minimizing wear and extending gear and bearing life.
Cooler Operation & Longer Gear Life
Significantly lowers operating temperatures while providing exceptional thermal and oxidative stability, resulting in smoother performance and reduced maintenance costs.

Frequently Asked Questions
It contains patented ceramic coating technology that actively forms a self-lubricating protective film on metal surfaces under extreme heat and pressure — something standard gear oils simply cannot do.
The ceramic coating seeks out areas of high friction and heat, bonding to the metal to dramatically reduce wear, lower operating temperatures, and provide superior boundary-layer protection even during dry starts or heavy loads.
Yes. TRI-EX² 75W-140 meets or exceeds API GL-5, API MT-1, MIL-PRF-2105E/D, Mack GO-J/GO-H, Eaton PS-386, Meritor O-81, ZF Freedomline, and Navistar TMS 6816.
Most customers report quieter operation, smoother shifting, and significantly lower differential temperatures almost immediately, along with improved fuel mileage and longer gear life.
We do not recommend Tri-Ex2 Gear Oil for Limited Slip differentials. We offer Tri-EX Limited Slip Gear Oils for these applications. It comes with the Limited Slip Additive blended in for maximum performance.
All TriboDyn TRI-EX² gear oils are proudly manufactured in our own ISO 9001 certified facility in the United States by a team of experienced tribologists who have engineered lubricants for aerospace, racing, and heavy industry for decades.
